Short, concise description of the idea
The ability to screen comments from a particular user or a particular IP address
Full description of the idea
Is there some way the ability to screen comments could be enhanced in order to allow both the screening of individual LJ users and individual IP addresses (assuming you already log those of all commenters)?
An ordered list of benefits
Wouldn't require that you see all comments before unscreening them.
Would allow you to block specific anonymous posters, which is now only possible for specific LJ posters.
An ordered list of problems/issues involved
Main drawback would likely be processor usage.
An organized list, or a few short paragraphs detailing suggestions for implementation
It seems like this could simply involve a list of lj users and/or IP addresses stored for each user. When an LJer's comment is submitted, it is checked against the list of lj users and screened if the name is among them. For anonymous posts (or perhaps for all posts, if the user logs all IP addresses), the IP address would be similarly checked against those in the list.
